Sweeping compound.



U ITED STATES PATENT OFFICE.

BER'IIIOLD SINGER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE PEROLIN COMPANYOF AMERICA, OF CHICAGO, ILLINOIS,'A CORPORATION OF ILLINOIS.

SWEEPING COMPOUND.

To all irhnin it may concern.

Be it known that I, llnmnoto Slxonn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois. haveinvented certain new and useful Improvements in Sweeping Compounds,ofwhich the following is a full, clear, and exact specification.

This invention relates to a composition or compound,

and process of making the same, designed to be placed upon the floorpreparatory to nnd iiiiring sweeping, for collecting or laying the dust,and it has for its object to provide a granular form of material forthis purpose in which each individual granule'or particle shall containwithin itself a quantity of dust-absorbing or collecting substances soheld by the said particles as to remain moist practically indefinitely.

With a view to the attainment of these ends, and the accomplishment ofcertain other objects which will hereinal'tcr appear, the inventionconsists in the-features of novelty which will now be more specificallydesciibed and pointed out in the claims. I

In carrying out my invention, i employ a suitable body materialcomprising small particles or granules, each individual granule ofwhichposscsses pores, so as to be capable of absorbing a liquid, ascontradistinguished from merely carrying a portion of the liquid on itsexterior, and these particles or granules I thoroughly impregnate orsaturate with a resinous-material in proportion suiiicient to fullyladen each. particle without having any free liquid, so thatthe'resultant ploduct will be a granular mass, or massof detached,separated particles, each containing within itself a quantity of theresinous liquid, and being capable of rolling freely upon the floor, orother surface, and bringing all 0 its sides into contact with the dustparticlcs, which adhere to the resinous material-by reason of theirmoist and viscous surfaces, which are retained in this moist conditionpractically i'udeiiuit ely, and

V the moisture of the surface thereof replenished'by the more liquidform of the resinous material contained further wi t hinthe pores of thegranule or body-particle.

As a suitable porous granule, or cornminuted body.- suhstunr-e, Iemploy-saw-dust, comminuted slag, or other like material, but preferablysaw-dust, because of its cheapness, its porous nature, and its cleaningproperties; and for the resinous material, I employ any resinonematerial and water, but preferably hard resin. To about one pound ofresin, I add 25 pounds of water, the resin being dissolved by a medium,preferably con- 'gpecification of Letters Patent. Applieation filedAugust 1,1906. Serial No. 328,736.

sisting of lye or potash, and by the aid of steam or other suitableheat, and after the resin is thoroughly dissolved, making a solution ofresinous material. While the liquid is still at a high degree of heat, Iadd thereto about 15 pounds of saw-diist, or a suiiicient amount toentire] y f absorb all the liquid and at the same time thoroughlysaturate all particles of the saw-dust without leaving rior insuilicient quantity to keep the exterior in that semi-moist conditionnecessary for collectingor laying the particles of dust with which itcomes in contact during the sweeping operation. A sweeping compoundcomposed of these ingredients will lay and collect the dust withoutstaining the floor or carpet.

The efficiency of the material thus described may be considerablyenhanced by the addition thereto of a quantity oi'saud, whi -h servesthe two-fold purpose of cutting the particles of saw-(first apart,avoiding the V possibility of the granules hanging together en masse,and securing the-scouring properties of the sand itself. With theproportions before mentioned, 40 pounds of sand maybe employed.

What I claim and desire to secure by Letters Patent, is.- p

'i'he herein-described composition of matter containing separate ordetached granules or particles, individually porous, and a solution of aresinous compound with which the individual pores are lmpregnated, ailin a mass of detached granules.

2. A composition of. matter for the. purpose specified .comprisingsawdust, a resinous material, and a sillcious material, said mixturebeing adapted to absorb dust, substantially as described.

3. The herein-described composition of matter containing saw-dustsaturated with resin soap in a mass of detached granules.

I). The hereinair-scribed composition of matter containing absorbentgranules, each individually porous, n solutlon of resin soap with whichthe individual pores of saidgranules are impregnated, n granulatedmaterial mixed therewith for separating said granules, all in a. stateof free detached granules.

5. The hereln describedcomposition of matter-containingindividually-porous granules, a resin soap with whtch the said granulesare impregnated,- and sand intermingled therewith.
